IRL shooting distances where much less what we do in AH.
At 200 yards (typical IRL shooting distance) .50 calibre shreds the enemy fighters.
In here buffs at 1000 yards .50 calibre are deadly, and at 800 yards 4*20mm cripple a fighter.
At 400 yards I lose parts unless I get cockpit hits from .50 cal (in Fw190's).
Many times I lose half a wing when an angry P47 shoot at that range, but can often RTB half winged.
I've been flying the F4u1 some, I get most kills when I fly RTB, not when I hit them, but I shoot at distance with high closure speed.
I'm advocating for shorter shooting ranges altogether, that will even out the differences (except them buffs if they still cripple 400 yards longer than other .50 calibres do).
